windows/mac editing interface

I will be working with someone on a project who uses mac based pro-cut 5 and I am builiding a windows based system probably with Adobe. What can be done to make the work I will do usable by the mac system (I know, get it together with regard to using the same system)?

We re-sell software from a company that creates tools to export projects from everything from FCP to Premiere to Avid to Combustion to AE and more. This might be for you. Automatic Duck is the name of the developer.
